from my understanding of this module, I wrote a simple script to permutation test. The outer loop is for generating random sequences for inner loop to use. I mean that, I do 1000 computation, for example. Each computation in inner loop will use 16 CPUs and other parameters to carry out a task dedicated by count_pwm_num(). But when I performed the task, I always got the complaint which is " Cannot fork: Cannot allocate memory at /perl5/Parallel/ForkManager.pm line 589"

Here is the code. 
foreach my $shuffle_id (1..$permutation) {
    my $pm     = Parallel::ForkManager->new( $multi_cpu_num );
    PFM:
    for my $pwm (@ciona_pwm_array) {
        $pm->start and next PFM;
        count_pwm_num($pwm,$seq_1,$seq_2);
        $pm->finish;
    }

    $pm->wait_all_children;
}

Please point out where is the error in my code.
